FIELD OF INVENTION

The present invention relates to a wearable device.

PRIOR ARTS

Wearable device denotes a portable device directly worn or integrated into the clothes or accessories of the user. At present, the wearable device is in the form of portable accessories connectable to cell phone or various terminals with partial calculation function. The mainstream product form thereof includes watch products supported by wrist such as watch and wristband; shoe products supported by foot such as shoes, socks or other wearable devices for legs to be developed in the future; glass products supported by head such as glasses, helmet and head band; and various non-mainstream products such as intelligent costume, bag, crutch and ornament.

Wearable device is not only a hardware device, but also a device implementing powerful functions by software support and data interaction or cloud interaction. Wearable device will greatly change our life and perception.

The alert modes of the conventional wearable device mainly involve sound alert and vibration alert. The sound alert is not applicable in many situations (i.e. during the meeting, cinema). And for the vibration alert, the wearable device contacts user's skin directly, especially the intelligent glasses class of wearable device will contact some sensitive part of human body, thus the vibration will bring unpleasant experience to user.

Content of the Present Invention

The technical problem to be solved by the present invention is to overcome the defect that the alert modes of the conventional wearable device will bring inconvenience and unpleasant experience to user. To solve this technical problem, the present invention provides a wearable device with quiet and comfortable alert mode for alerting events.

The present invention solves the above technical problem by the following technical solution: a wearable device, comprising at least one contact area for contacting a wearing object, a temperature detecting circuit, at least one temperature regulating module and a control chip;

-   -   the temperature detecting circuit is configured to detect the         temperature of the contact area when events happen as a first         temperature;     -   the control chip is configured to, within a preset interval         since events happen, control the temperature regulating module         to change the temperature of the contact area on the basis of         the first temperature to alert events happening.

The wearable device may be an intelligent watch or a pair of intelligent glasses, and the contact area can be contacted with user's skin, to make user sense the change of temperature of the wearable device. Both the highest temperature and the lowest temperature achieved at the contact area fall within the acceptable temperature for human body.

To make user easier to sense the change of temperature, the wearable device of the present application changes temperature based on the temperature when events happen, wherein the temperature when events happen is obtained by the temperature detecting circuit, and thus able to provide user with a temperature difference to make user sense the change of temperature conveniently.

The present application can provide several alert modes, that is to say, by making temperature change on the basis of the first temperature three alert modes can be provided. The three alert modes can correspond to different types of events, and said events include foreign event and intrinsic event. For example, the wearable device is an intelligent watch capable of receiving message and answering phone call and provided with alert function notebook, and the intelligent watch can be set to make the temperature of the contact area increase on the basis of the first temperature when there is an alert of receiving a message (temperature of the contact area increases), to make the temperature of the contact area decrease on the basis of the first temperature when there is an alert of notebook (temperature of the contact area decreases), and to make the temperature of the contact area increase and decrease alternately on the basis of the first temperature when there is an alert of receiving a phone call (temperature of the contact area increases and decreases alternately).

The present application provides user with quiet and comfortable alert modes which are several, and can set different alerts for different types of events.

Preferably, the temperature regulating module includes a temperature regulating component which contacts the contact area via a heat conductive element or contacts the contact area directly.

Preferably, the wearable device further includes at least one temperature feedback circuit, and the temperature regulating module includes at least one Peltier. The temperature feedback circuit is configured to feedback the temperature of the Peltier to the control chip, and the control chip is further configured to supply power to the Peltier.

Peltier, i.e. semiconductor chilling plate, is a refrigeration technology for generating negative thermal resistance, and the advantage thereof is that there is no active component and it can be applied to some applications with limited space. By means of Peltier effect, when direct current flows through electric couple comprising two different materials in series, heat is absorbed and discharged respectively at two ends of the electric couple, and the refrigeration and heating can be achieved. Herein, the surface of the Peltier for absorbing heat is refrigeration surface, and the surface of the Peltier for discharging heat is heating surface.

Preferably, the temperature regulating module further comprises a current direction converting circuit, and the Peltier connects to the control chip via the current direction converting circuit. The control chip is configured to control the direction of the current transferred from the current direction converting circuit to the Peltier, so as to control the side of the Peltier directly contacting the contact area or contacting the contact area via the heat conductive element to switch between the refrigeration surface and the heating surface.

By means of the temperature feedback circuit, the control chip can obtain temperatures of the refrigeration surface and the heating surface of the Peltier, and thus control the supply current of the Peltier so as to control the temperature of the contact area. By means of the current direction converting circuit, the control chip can control the direction of the current transferred to the Peltier so as to achieve the switching between the heating surface and the refrigeration surface of the Peltier without moving the Peltier.

Preferably, the temperature regulating module further includes a moving device, and the control chip is configured to control the Peltier to work continuously, wherein:

-   -   when no event happens, control the moving device to retain the         Peltier in such condition: the refrigeration surface of the         Peltier is relatively close to a self-heating element within the         wearable device, and the heating surface thereof is relatively         far away from the contact area or the heat conductive element;     -   when events happen, control the moving device to place the         Peltier to make the heating surface of the Peltier contact the         contact area directly or contact the contact area via the heat         conductive element.

To make the temperature of the contact area increase rapidly, the Peltier works continuously. When no event happens, the heating surface is away from the contact area such that user will not feel temperature increase. When events happen, the moving device makes the heating surface contacted the contact area directly or indirectly. Since the heating surface of the Peltier always maintains at relative higher temperature, when the heating surface contacts the contact area, heat will be rapidly transferred to the contact area, such that the temperature of the contact area increases rapidly.

Moreover, due to the characteristic of Peltier that heating by one surface and refrigerating by the other surface, when the Peltier is in working condition without event happening, placing the refrigeration surface close to the self-heating element within the wearable device and using the refrigeration surface to decrease the temperature of the self-heating element, wherein said self-heating element can be a battery or the control chip of the wearable device.

Preferably, each Peltier is constituted by several sub-Peltiers in parallel, each sub-Peltiers has a central axis, and all of the central axes of the sub-Peltiers are coplanar and in parallel with each other. In stationary, all of the heating surfaces of the sub-Peltiers are coplanar. The temperature regulating module further includes a driving device, and the control chip is configured to control the driving device to drive all of the sub-Peltiers to make them rotate around the central axes synchronously, such that the sides of all the sub-Peltiers directly contacting the contact area or contacting the contact area via the heat conductive element switch between the refrigeration surface and the heating surface.

To make the temperature of the contact area switch more rapidly to give more obvious prompt to user, each Peltier is divided into several sub-Peltiers. When the heating surfaces of the sub-Peltiers contact the contact area, the wearable device can prompt user by increasing temperature. By the sub-Peltiers rotating the refrigeration surface is approached to the contact area rapidly which makes the temperature of the contact area decrease rapidly, and the wearable device prompts user by decreasing temperature. The switching between the heating surfaces and the refrigeration surfaces can be achieved by the rotation of the sub-Peltiers.

All of the heating surfaces of the sub-Peltiers are coplanar, which means that all of the heating surfaces of the sub-Peltiers are coplanar when they contact the contact area directly or indirectly, while all of the refrigeration surfaces thereof are coplanar. That is to say, when the wearable device alerts user, all of the heating surfaces and the refrigeration surfaces are placed on the respective planes. For example, when the wearable device increases temperature as a prompt, all of the heating surfaces of the sub-Peltiers are located at the same plane, and one side of said plane is used to contact the contact area.

In addition, these synchronously rotating sub-Peltiers can be easily controlled. Specifically, the Peltier in prior art is unitary. However, in the present invention, the Peltier is constituted by several sub-Peltiers, and these sub-Peltiers can rotate in a smaller space so as to achieve fast switching between the heating surface and the refrigeration surface.

Preferably, the driving device includes a traction belt and a power device, and the power device is configured to pull the traction belt to make all of the sub-Peltiers rotate around the central axes synchronously.

The traction belt and the power device can operate to make the sub-Peltiers rotate synchronously.

Preferably, the wearable device is an intelligent watch.

The temperature detecting circuit, the temperature regulating module and the control chip are disposed inside the dial of the intelligent watch, while the contact area is disposed on the inner surface of the dial; or

-   -   the temperature detecting circuit and the temperature regulating         module are disposed inside the band of the intelligent watch,         and the control chip is disposed inside the dial of the         intelligent watch, while the contact area is disposed on the         inner surface of the band.

Preferably, the control chip is configured to, within the preset interval, control the temperature regulating module to adjust the temperature of the contact area to M+N degree Celsius or M−P degree Celsius;

M is the first temperature, and both of N and P are larger than 0 and less than or equal to 15.

By properly regulating the temperature of the contact area, user can comfortably feel the change of the temperature.

Moreover, the temperature detecting circuit is preferably NTC (short of Negative Temperature Coefficient, with the meaning of negative temperature coefficient) circuit.

The present invention further provides a wearable device, comprising: at least one contact area for contacting a wearing object, a temperature detecting circuit, at least one temperature regulating module and a control chip;

-   -   the temperature detecting circuit is configured to detect the         temperature of the contact area when events happen as a first         temperature;     -   the control chip is configured to, within a preset interval         since events happen, control the temperature regulating module         to increase the temperature of the contact area on the basis of         the first temperature to alert events happening, and the         temperature regulating module is an electric heating element.

The use of the electric heating element for increasing temperature to alert events happening can reduce the cost of the wearable device.

By utilizing the knowledge of the present technical field, the above optimum solutions can be combined to obtain the preferred embodiments of the present invention.
